[QUOTE="Burnham Beech, post: 864310, member: 175046"] Thanks for all the replies so far. I have tried +5/-5 Mhz and got nothing. Tried blind scan over 12515GHz and got nothing. The LNB on the 1.2m dish is not an IBU (Inverto Black Ultra). It is C120 Inverto coupled with the correct Channel Master feedhorn which I set up six years ago - all giving good service up to now. The cabling is quite old and may have deteriorated. But that does not explain why the old Duo has no problem with these high frequencies - using exactly the same cabling, dish & LNB - but that the brand new Duo2 does have a problem. New LNB has been ordered (coincidentally an IBU!), will test and report when it arrives. [/QUOTE]
